CELEBRITY SHOE-IN: Celebrity stylist Johnny Wujek may be the next one to branch out to the role of designer. But rather than create pricy baubles à la Andrea Lieberman for Mouawad, Wujek is designing affordable shoes for Solo Inc. under the label Johnny Wujek for Modern Vintage. The first season, this fall, was comprised of gladiator sandals and picked up by Nordstrom, Intermix, Zappos.com and Shopbop.com (pal Mischa Barton was also spotted wearing them around town last summer). The spring collection captures another trend: the chunky platform sandal in neutrals and neons. This time, Saks Fifth Avenue, Bloomingdale’s, Neiman Marcus and American Rag Cie have placed orders for the February delivery. At $295 retail, the shoes may prove to be a true commercial hit, reinforced by another trendsetting pal, Rachel Bilson, who has already placed an order in size 5 1/2. If not, Wujek can always stick with styling his clients Kate Mara, Katy Perry, Amber Heard and Bryce Dallas Howard.
